"Bjorn Lomborg is a highly polarizing figure, and his credibility is a subject of intense debate among scientists, economists, and policymakers.

Cambridge University Press & Assessment

While he holds a PhD in political science and is known for his work in statistics, the mainstream scientific and academic communities broadly view him as lacking credibility on environmental and climate science. Critiques of his work typically fall into several distinct areas:

Scientific Consensus vs. Cherry-Picking:

Scientists frequently criticize Lomborg for "cherry-picking" data, using outdated economic models, and misinterpreting or misrepresenting the conclusions of the very researchers he cites. Organizations like Climate Feedback frequently evaluate and challenge his claims.

Lack of Domain Expertise:

Lomborg is not a climate scientist. Most of his writing appears in op-eds in right-leaning publications that do not undergo rigorous scientific peer review, rather than in peer-reviewed environmental or climatology journals.

Controversial History with Integrity:

In 2003, the Danish Committees on Scientific Dishonesty (DCSD) concluded that his first book, The Skeptical Environmentalist, was scientifically dishonest due to systematic misinterpretation of data, though this ruling was later overturned by the Danish Ministry of Science on procedural grounds.

Environmental economists and institutions"such as the Grantham Research Institute on Climate Change and the Environment"heavily criticize his economic calculations, stating that they drastically underestimate the potential damages of unmitigated global warming.

Therefore, mainstream climate experts generally do not consider him a credible source on the topic.
